Due to a lack of resources, rural communities often face challenges when planning catastrophic events. This project involved applying systems thinking and model-based systems engineering to develop a proof-of-concept, multi-method computer simulation and then determining whether the simulation could be used to assess the efficacy of disaster planning approaches on health outcomes in rural communities, as a function of primary healthcare. The project focus was a rural or non-urban healthcare system experiencing a natural hazard. Both system dynamics and discrete event models were incorporated to represent subsystem operations, crucial disaster responses, as well as three key response systems: public health, emergency management, and healthcare. The subsystem models included several components: policies/procedures, communications,resources, exercises/drills/training, healthcare space and staff, and the flow of affected people into and through the *** combined simulation can serve as a first step to a more comprehensive approach to helping rural communities achieve more efficient and effective healthcare planning for disaster responses.

It is proposed that where sexually selected vocal communication is an honest signal, the call production rate is predicted to change throughout the breeding season. Male leopard seals call underwater for many hours each day over their three- to four-month breeding season, and it is hypothesized that a decrease in calling rate would be associated with the declining body condition of smaller males. The calling rates of leopard seals were measured （N= 49 recordings） and com- pared between seals of different size classes throughout the breeding season. Male leopard seals produce their calls at more stable rates as they become larger. In this study, larger male leopard seals adopted a strategy of consistent underwater calling throughout the breeding season, whereas there was a breakdown in the calling stereotypy of the smaller males at its height. Toward the end of the breeding season, the smaller seals produced fewer calls in shortened calling bouts, and they took more rest periods. Therefore, underwater calling may represent an honest signal in the leopard seal. For marine mammals that call underwater, the production of repetitive sequences advertises the breath-holding ability of the caller to the listeners, and this ability may be related to male stamina and endurance, thus representing an honest signal that could be widespread in other species.

purpose: The purpose of this study was to determine whether practicing athletic trainers(ATs) were using the stepwise progression to make return-to-play(rTp) decisions after concussion and to determine what factors influenced their decision to use the stepwise ***: A total of 166 ATs(response rate = 16.6%) completed a 21-item questionnaire that evaluated participant demographics, methods of concussion management, and rTp decision-making using the stepwise progression. Descriptive statistics and a logistic regression were completed to analyze ***: Factors such as education level(p = 0.05) and number of concussions treated(p = 0.05) predicted use of the stepwise progression,whereas sex(p = 0.17), employment setting(p = 0.17), state law(p = 0.86), and years practicing(p = 0.17) did not predict whether ATs were following the stepwise ***: The majority of the ATs from this study are employing the stepwise progression to safely return athletes to play after sustaining a concussion. This demonstrates that ATs are providing a standard of care for concussed athletes across various athletic training settings; however,having a graduate degree and treating more concussions per year are predictors of whether an AT follows all steps of the stepwise progression.
